Abstract

The therapeutic goal for hepatitis B virus (HBV) infection is HBs antigen (HBsAg) seroclearance, which is achieved through 48-week pegylated interferon (Peg-IFN) therapy. This study aimed to identify predictive biomarkers for sustained HBsAg reduction by analyzing serum microRNAs. Twenty-two consecutive chronic HBV infection patients negative for HBe antigen (HBeAg) with HBV-DNA levels <5 log copies/mL, alanine aminotransferase (ALT) <100 U/L, and compensated liver functions, were enrolled. The patients were subcutaneously injected with Peg-IFNα-2a weekly for 48 weeks (treatment period), followed by the 48-week observation period. HBsAg 1-log drop relative to baseline levels recorded at the end of the observation period was considered effective. Sera were obtained at weeks 0 and 24 during the treatment period analyzed for microRNAs. The microRNA (miRNA) antiviral activity was evaluated in vitro using Huh7/sodium taurocholate cotransporting polypeptide (NTCP) cells. As a result, six patients achieved the HBsAg 1-log drop after the observation periods. Comparison of serum microRNA levels demonstrated that high miR-6126 levels at week 24 predicted HBsAg 1-log drop. Furthermore, miR-6126 reduced HBsAg in culture medium supernatants and intracellular HBV-DNA quantities in Huh7/NTCP cells. In conclusion, high serum miR-6126 levels during Peg-IFN therapy predicted the HBsAg 1-log drop 48 weeks after the completion of therapy. In vitro assays revealed that miR-6126 was able to suppress HBsAg production and HBV replication.

抽象

乙型肝炎病毒(HBV)感染的治疗目标是HBs抗原(HBsAg)血清清除,这是通过48周聚乙二醇化干扰素(Peg-IFN)治疗实现的。本研究旨在通过分析血清microRNA来鉴定持续降低HBsAg的预测生物标志物。共纳入22例连续慢性HBV感染HBe抗原阴性的患者(HBeAg),HBV-DNA水平<5 log拷贝/ mL,丙氨酸氨基转移酶(ALT)<100 U / L,肝功能代偿。每周皮下注射Peg-IFNα-2a持续48周(治疗期),然后进行48周的观察期。相对于观察期结束时记录的基线水平的HBsAg 1-log下降被认为是有效的。在治疗期间的第0周和第24周获得血清,分析微小RNA。使用Huh7 /牛磺胆酸钠协同转运多肽(NTCP)细胞在体外评估microRNA(miRNA)抗病毒活性。结果,6名患者在观察期后达到HBsAg 1-log下降。血清microRNA水平的比较表明,第24周的高miR-6126水平预测HBsAg 1-log下降。此外,miR-6126降低培养基上清液中的HBsAg和Huh7 / NTCP细胞中的细胞内HBV-DNA量。总之,Peg-IFN治疗期间的高血清miR-6126水平预测治疗完成48周后HBsAg 1-log下降。体外测定显示miR-6126能够抑制HBsAg产生和HBV复制。
